Sacrificial Biofabrication for Vascularization: Concept, Materials, Technologies, and Applications

open access: yesAdvanced Materials, Volume 38, Issue 2, 8 January 2026.
Vasculature is indispensable for tissue viability in regenerative medicine. The sacrificial biofabrication enables precise fabrication of vascular channels by using temporary templates that are subsequently removed. This review defines the concept and delves into sacrificial materials, surrounding materials, fabrication technologies, and biomedical ...

Synthesis of Polysubstituted Tetrahydro‐1,4‐Thiazepines by Rhodium‐Catalyzed Ring Expansion of Dihydro‐1,3‐Thiazines with Diazoesters

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 2, January 2026.
A rhodium(II)‐catalyzed ring expansion of stereodefined dihydro‐1,3‐thiazines with diazomalonates gives 1,4‐thiazepines via a sulfonium ylide rearrangement. The reaction shows a cis/trans reactivity divergence arising from different metal coordination, as revealed by experiments and density functional theory studies.

Cycloaddition of CO2 to Epoxides Using Bifunctional Triphenylphosphonium Catalysts

open access: yesChemCatChem, Volume 18, Issue 1, 15 January 2026.
Metal‐free phosphonium‐pyridine catalysts enable the solvent‐free fixation of carbon dioxide with diverse epoxides at 1 amt, including challenging bio‐based terpenes. ABSTRACT A series of pyridine‐grafted triphenylphosphonium salts [Ph3P+R]Cl− (R = benzyl (1), pyridine‐2‐ylmethyl (2), pyridine‐3‐ylmethyl (3), and pyridine‐4‐ylmethyl (4)) were ...
